latter study did not comprise patients undergoing TKA, considered a relatively small sample, and was performed in a tertiary care center. So, a direct comparison of preoperative expectations regarding THA or TKA and their fulfillment in a general hospital setting is, as far as we know, lacking.This is relevant because in the Netherlands, most of these operations are performed in this setting.
The aims of the present study were:
1. To assess patients’ preoperative expectations of the outcome of THA or TKA regarding a number of aspects of functioning.
2. To determine to what extent each expectation is fulfilled 1 year after surgery in general hospital setting.
